154 NORTH AMERICAN BLATTIDAE 



The Group Pseudomopites includes species nearly all of which 

 are very brilliantly colored. The eyes show a tendency to bulge 

 latero-dorsad, this greatly developed in the genus Pseudophyllo- 

 dromia. The antennae in some genera are plumose to varying 

 degrees in different species. The tegmina and wings are glossy. 

 The tegmina are narrow, and in many genera show the median 

 width less than the width elsewhere, the discoidal sectors are longi- 

 tudinal, in some genera radiating slightly distad; a striking condi- 

 tion is developed in certain genera, in which these sectors form a 

 distinct angle at the apex of the anal field, either in their direction 

 or with the ulnar vein. The wings have few rami of the ulnar 

 vein, these complete.

The present genus is not as widely separated from Psendophyl- 

 lodromia as has been supposed, and should be placed after, not 

 before, that genus, in linear arrangement. 



The genus apparently splits into two very distinct groups, while 

 these again divide into minor groups. Of these latter, it would 

 appear that, of the species before us, septentrionalis, discoidalis 

 and intercepta (all North and Central American) are members 

 of one group, while oblongata, ~^'^ affinis, angitsta and annidicornis 

 (all South American) are members of another. The species of 

 the first group are broader, with broader tegmina and less plumose 

 antennae, than those of the second. Between these groups, the 

 Mexican cincta should be placed; having antennae as in the first, 

 but form and tegmina as in the second. 



The numerous described species of this genus are confined to 

 tropical America, with the exception of septentrionalis, here de- 

 scribed. We are not satisfied that the complex does not include 

 several genera, but in any case we are convinced that the species 

 described below is congeneric with the genotype. 



Ml We have, unfortunately, no material of (>l)lou'^ala liefore us, or in fart any sjiecimens 

 of the genus from Surinam, the locality from which it was described. From study of the 

 Linnaean and DeGeerian descriptions and figure, however, we are satisfied that the 

 position of this species, the genotype, is as indicated here.
